WHEEL AND DEEOUNTAELE RIT/.

nppiication ined April i9, i919. sei-iai No. 291,192.

To all whom may concern:

Beit known that l, JOSEPH G. SWAIN, a citizen of the rUnited t States, residing at Akron, in the county of Summit, State of Ohio, have invented certain new and yuseful improvements in Wheels andDemount-able Rims, of which the following is a specification. j

This invention relates to demountable rims for carrying pneumatic tires and the purpose is to perfect the inountingof the wheel so as to reduce as much as possible the lifting required in mounting' and fdeniounting the tire. Particularly in the use of large size pneumatic tires, an objectionable feature arises in the ordinary construction yof rims and wheels, as an excessive amount of space is necessary to permit the valve stein. to be withdrawn as the rim is rocked oif the wheel. It is the purpose of this invention to so construct the wheel that the rim may be slid onto the wheel without providing a large space between the wheel and therirn.l and obviating the necessityof lifting` the heavy rim and tire. For this purposethere has been sul'istituted for the regular valve stem hote, slot preferably entering from the side of the wheel., through which the valve stem can be passed without the necessity of lifting, tipping;7 or rockingthe rim as in the ordinary construction. .l have also provided means for covering thc slot so that dirt and water will be excluded from the slot and mud will not become caled therein.

These and other objections will be apparent as the description proceeds and it is understood that modifications may be made in the form of invention without sacrificing any of its benefits.

in the drawings:

i is a side elevation of a portion of the wheel.

Fin: 2 is a cross section through the valve stein.

Fig. 2 is a plan view of the inside of the wheel at the valve stern.

Fig, 4; is a perspective vview oi' the clip or cover plate.

The invention herein may beeinbodied in many diii'erent forms, one of which. is shown in the drawings in which l represents a wheel structure. This wheel may be of any preferred type, that shown being a cast steel wheel of any well known type, the outer surface of which is formed as a. cylindeiyexcept for a flange or rib 2, the upper surface of which is formed as akcone to provide a seat for a corresponding` conical rib 3 on the underside of the demountable or removable rim 4. This rim may be of any desirable form,

that shown being` of the type known as a straight-side quick detachable rim adaptable Lto receive a straight-side tire 5. `The fo 'in of the rim is immaterial as it may be made to receive any Well known type of tire. The inner tube of the tire is shown at 6 and the valve stein of any well known construction at 7.

On the outer side of the rim is formed an inwardly extending rib 8, the underside of which is beveled and closely adjacent the Youter surface of the wheel, a locking ring 9,

La well known form. but my invention is not Vlimited for usewith this particular mount ,ingr and may be adapted for use with` any form of securing means. V

In order tor provide for removal. of the rim and tire by lateral. sliding action to avoid the lifting or tilting of the riin, with its consequent disadvantages, it is desirable to afford means for permitting the tire valve to pass out at the side of the wheel. This means comprises preferably a slot or elongated recess i2, which will allow a lateral movement of the rim on the wheel suiiicient to permit the removal of the rim without the excessive tilting' or rocking' found in the present forms of demountable rims.

The slot l2 is shown as opening` from thc side ofthe wheel which will. permit the lateral movement of the riin without excessive tiltin 1; and, while this construction is preferred; the invention herein is not so limited.

Inorder to keep the slot free 'from caked mud or dirt, and to protect the inside of the rim and valve stein and tire from water,

dust, or mud, there is provided a cover plate or clip which may be of any preferred form.

,ln the present form of the invention the clip is shown at 13 and comprises an approximateliV flat major portion ll. the. end of which is provided with an aperture l5 which passes over the valve stein. A side flange 16 may he forn'ied on the end of the clip which ma)y be seated in a recess in the side of the wheel so as to come flush with the main body. The end of the clip is turned'backward at l to parallel the main portion and may be received in a recess in the outer surface of the wheel.

The dust cap is shown at 1S, and, when screwed down onto the valve stem, contacts the upper surface of the cover plate. It will be seen that the clip or cover plate is held in place by the valve stein and dust cap, and further by the under side of the clamping ring.

Although the invention has been described in more detail than is necessary for an understanding of it, l am not limited to the exact form or proportions and location of parts, but mayv modifiT the invention in a number of ways without departing therefrom.

I claim:

1. In a demountable rim construction, a wheel and demountable rim, the wheel being provided with a slot opening from the side thereof, to receive the valve stem and .permit the removal of the rim without tipping, an angular plate having,- two parallel portions and a third portion connecting' the parallel portions fitted over the slot and covering it from three sides7 in combination with means on the valve stem adapted to Contact the plate and hold it in place.

2. In a demountable rim construction, a wheel and deinountable rim7 a clamping ring` between the wheel and the rim, the

Miedos? wheel beine' provided with a slot opening from the side thereof to receive the valve stein and permit the removal of the rim without tipping, a plate, one arm of said plate covering the upper surface of the slot and provided with an aperture to receive the valve stem, a second arm covering the side of the wheel at the slot and a. third arm parallel to the first named arm receivable under the clamping rino,

3. In a demountable rim construction, a wheel and demountable rim, a clamping ring between the wheel and the rim7 the wheel being` provided with a slot opening from the side thereof to receive the valve stem and permit the removal of the rim without tipping, a plate, one arm of said plate covering the upper surface of the slot and provided with an aperture to receive the valve stem, a second arm covering` the side of the wheel at the slot and a third arm parallel to the first named arm receivable under the clamping ring in combination with a dust cap screwed onto said valve stern and securingl the .plate in position.

4. A wheel having a iiXed rim with a slot formedV therein which extends inwardly from a side thereof, a demountable rim adapted to accommodate a tire with a valve stem thereon, a wedge ring for holding the rim to the fixed rim, a cover co-operating with the inner side and the outer side of the fixed rim and covering the said slot, said cover having an opening through which a valve stem may extend and also provided with a portion adapted to extend between a surface of the fixed rim and the wedge ring.
